Description

A low-voltage intelligent circuit breaker for distributed photovoltaic measurement terminals and its use method Technical Field

[0001] The present invention relates to the technical field of low-voltage switches, and in particular to a low-voltage intelligent circuit breaker for distributed photovoltaic measurement terminals and a method of using the same. Background Art

[0002] A low-voltage circuit breaker is a switching device that can not only connect and disconnect normal load current and overload current, but also connect and disconnect short-circuit current. In addition to playing a control role in the circuit, the low-voltage circuit breaker also has certain protection functions, such as overload, short circuit, undervoltage and leakage protection. There are many ways to classify low-voltage circuit breakers. According to the usage category, there are selective type (protection device parameters are adjustable) and non-selective type (protection device parameters are not adjustable). According to the arc extinguishing medium, there are air type and vacuum type (currently most domestic products are air type). It is an electrical appliance that has both manual switching function and automatic loss of pressure, undervoltage, overload, and short-circuit protection. It can be used to distribute electrical energy, start asynchronous motors infrequently, and protect power lines and motors. When they suffer serious overload or short circuit and undervoltage faults, they can automatically cut off the circuit. Its function is equivalent to a combination of a fuse switch and an over- and under-temperature relay.

[0003] However, existing low-voltage circuit breakers have some defects when in use: the existing low-voltage circuit breakers are internally provided with an automatic tripping mechanism, but when in use, the existing automatic tripping mechanism uses a torsion spring to drive the device to trip. Since the torsion spring needs to be manually operated when returning to its position, manual closing is required when the circuit breaker is closed. Generally, a large number of circuit breakers are used in circuits, which makes manual closing more troublesome. At the same time, since there is current in the circuit breaker, it is easy to be electrocuted when the human hand is wet when closing the circuit breaker, which also poses certain risks when in use.

The circuit breaker includes a drive unit 200, which includes a remote controller 201, a motor 202, a screw 203, a gear assembly 204 and a rotor 205, as well as a first push plate 206 and a second push plate 207.

[0037] Example 2

[0038] 1 to 3 , a second embodiment of the present invention is shown, which differs from the first embodiment in that the gear assembly 204 includes a first gear 204a, a second gear 204b, a third gear 204c, a fourth gear 204d, a fifth gear 204e, a sixth gear 204f, a seventh gear 204g, and an eighth gear 204h; the first gear 204a is meshed and connected with the screw 203, the first gear 204a is fixedly connected to the second gear 204b via a connecting shaft, the second gear 204b is meshed and connected with the third gear 204c, the runner 205 is fixedly connected to the third gear 204c, the third gear 204c is meshed and connected with the fourth gear 204d, and the fourth gear 204d is meshed and connected with the fifth gear 204e.

[0040] It should be noted that a rotating shaft 105a is provided on the rocker 105 near the first push plate 206, and the bottom of the rotating shaft 105a is fixedly connected to the bottom box 101. A limiting hole 105b is provided on the rocker 105, and the width of the blocking block 107a-1 is greater than the width of the limiting hole 105b. The purpose is to enable the jumping rod 107a to drive the rocker 105 to move.

[0041] Furthermore, an opening 101c is provided on one side of the bottom box 101, and the position of the opening 101c corresponds to the position of the closing display panel 205a; a fixing plate 101d is fixedly connected to the interior of the bottom box 101, and a fixing sleeve 101e is movably connected to one side of the fixing plate 101d, and the interior of the fixing sleeve 101e is provided with holes that are adapted to the specifications of the incoming line 106 and the incoming and outgoing line 110. By setting the fixing plate 101d and the fixing sleeve 101e, the incoming line 106 and the incoming and outgoing line 110 can be fixed, thereby avoiding the problem of the incoming line 106 and the incoming and outgoing line 110 being entangled inside the gear.

[0043] The remaining structures are the same as those of Example 1.

[0044] During use, the background running device is used to operate the remote controller 201, prompting the motor 202 to drive the screw 203 to rotate. At this time, the screw 203 will drive the first gear 204a to rotate, and the first gear 204a will drive the second gear 204b to rotate. At this time, the second gear 204b will drive the third gear 204c to rotate, and the fourth gear 204d will drive the fifth gear 204e to rotate, thereby prompting the first push plate 206 to drive one end of the seesaw 105 to move downward. At this time, the other end of the seesaw 105 will be connected to one end of the first connecting piece 104, thereby achieving the purpose of automatic closing, thereby avoiding the trouble of traditional manual pushing of the gate.

[0045] Example 3

[0046] 1 to 5 , a third embodiment of the present invention is shown. This embodiment differs from the second embodiment in that a second push plate 207 is connected to the side wall of the eighth gear 204h, an end of the second push plate 207 away from the eighth gear 204h is movably connected to the bimetallic strip 109, and a closing display panel 205a and a tripping display panel 205b are fixedly connected to one side of the runner 205.

[0047] When the distributed photovoltaic measuring end is closed with a low-voltage intelligent circuit breaker, the background operation device is used to operate the remote controller 201, so that the motor 202 drives the screw 203 to rotate, and the screw 203 drives the first gear 204a to rotate. At the same time, the first gear 204a drives the second gear 204b to rotate, the second gear 204b drives the third gear 204c to rotate, and the fourth gear 204d drives the fifth gear 204e to rotate, thereby causing the first push plate 206 to drive one end of the seesaw 105 to move downward, and the other end of the seesaw 105 will be connected to one end of the first connecting piece 104, thereby achieving the purpose of automatic closing and avoiding the trouble of traditional manual pushing of the gate.

[0048] When the distributed photovoltaic measuring end low-voltage intelligent circuit breaker encounters an overload of the wires, the bimetallic strip 109 bends, and one end of the bimetallic strip 109 pushes one end of the second push plate 207 to move upward, and the eighth gear 204h rotates; the eighth gear 204h drives the seventh gear 204g to rotate, the seventh gear 204g drives the fourth gear 204d to rotate, the fourth gear 204d drives the fifth gear 204e, the first push plate 206 moves upward, and one end of the seesaw 105 moves away from the first connecting piece 104, thereby blocking the power supply and tripping. At the same time, the seventh gear 204g drives the fourth gear 204d to rotate, and the first gear 204d drives the third gear 204c to rotate. At this time, the trip display panel 205b will be displayed on the outside of the bottom box 101, thereby reminding the staff that there is a fault in the wires.

[0049] When the distributed photovoltaic measurement end uses a low-voltage intelligent circuit breaker that encounters a short circuit in the wires, the current in the electromagnetic coil 107 will increase. At this time, using the electromagnetic principle, the iron block inside the electromagnetic coil 107 drives the jumper 107a to move downward, and one end of the seesaw 105 is away from one end of the first connecting piece 104, thereby blocking the flow of current and causing tripping. At the same time, the seesaw 105 moves in connection with one end close to the first connecting piece 104. Due to the rotating shaft 105a, the seesaw 105 uses the lever principle, and the end of the seesaw 105 away from the first connecting piece 104 pushes the first push plate 206 to move upward. The fifth gear 204e rotates under the drive of the first push plate 206, and the fifth gear 204e drives the fourth gear 204d to rotate. The fourth gear 204d drives the third gear 204c to rotate, and the wheel 205 starts to rotate. At this time, the trip display board 205b will be displayed on the outside of the bottom box 101, thereby reminding the staff that there is a fault in the wires.
